5 Claims. '(01. 1s.2 3s) This invention relates to certain improvementsin hair waving devices in which a pre-formed tress of hair is subjectedto the action of an exothermic material which, when moistened, will ofitself generate heat sufficient to impart a socalled permanent wave tothe tress.

This invention comprises a hair waving device in which a charge ofexothermic material in the form of a coiled sheet is inserted into atube of absorbent material; a perforated tube of metal or other suitablestiff material being preferably used to provide a rigid support for thewound tress.

Practical embodiments of my invention are represented in theaccompanying drawing, in which:

Fig. 1 represents the hair waving device' in side elevation as in use;

Fig. 2 represents a longitudinal central section through the form ofhair waving device in which the tress of hair is wound upon a perforatedtube of stiff material and the absorbent tube is inserted between theperforated tube and the coiled sheet impregnated withthe exothermicmaterial;

Fig. 3 represents a similar section through the a form of hair wavingdevice in which the tress of hair is wound upon the absorbent tube andthe perforated tube is inserted between the absorbent tube and thecoiled sheet impregnated with the exothermic material; and I Fig. 4represents a section similar to Fig. 3, with the perforated tubeomitted.

The outer wrapper is denoted by 1, which wrapper may be made of anysuitable non-absorbent material, such as parchment paper, foil, or thelike. The clamp is denoted by 2, which clamp may be of any well known orapproved form. It is to be understood that any suitable protective pad,not shown herein, may be inserted between the clamp 2 and the scalp ofthe person being treated.

The perforated tube is denoted by 3, which tube may be made of metal orother suitable stiff material.

The tube of absorbent material is denoted by 4, which tube is adapted tobe moistened by water or by a suitable hair waving solution, such asthat used for moistening the tress.

The charge of exothermic material is shown as a coiled sheet 8impregnated with the exothermic material.

In the form shown in Fig. 2, the tress of hair 9 is wound upon theperforated tube and the tube of absorbent material 4 is inserted betweenthe coiled sheet 8 impregnated with the exothermic material and the saidperforated tube.

In the form shown in Figs. 3 and 4, the tress of hair 9 is shown aswound upon the tube of absorbent material 4, and the perforated tube 3is shown as inserted between the coiled sheet 8 impregnated with theexothermic material and the said tube of absorbent material.

In the form shown in Fig. 4, the perforated tube 3 is omitted, thecoiled sheet impregnated with the exothermic material being inserteddirectly into the bore of the tube of absorbent material.

The exothermic material impregnated sheet 8 may be of any suitablematerial, such, for instance,

as blotting paper or cloth.

In practice, the tress of hair. 9 is wound either upon the perforatedtube 3 as shown in Fig.2, or upon the tube of absorbent material 4 asshown inFigs. 3 and 4. The tress 9 may be moistened either before orafter it is wound, by a suitable waving solution, such for instance asan ammonia solution. The tube 4 of absorbent material is moistened bywater or by a suitable hair waving solution, such as that used formoistening the tress 9. The coiled sheet 8 impregnated with theexothermic material may then be inserted into the bore of the moistenedtube of absorbent material in the form shown in Fig. 2 or into the boreof the perforated tube in the form shown in Fig. 3 or directly into thebore of the tube of absorbent material as shown in Fig. 4. The outerwrapper 1 is then wrapped around the wound tress and may be secured atthe scalp end of the tress by the clamp 2, the outer end of the'wrapperbeing twisted together to close the same.

The exothermic action starts at once because of the application ofmoisture by the wetted tube of absorbent material to the coiled sheetimpregnated with the exothermic material. Heat is thus set up within thedevice sufiicient to impart a so-called permanent wave to the preformedtress without requiring application of heat from an outside source.

It will be seen that the outside wrapper serves to confine the heat to alarge extent within the device, the steam generated by the reaction ofthe water and/ or waving solution with the exothermic material beingpermitted to escape through the crimped outer end of the said wrapper.

This application is a division of my 'copending application filedNovember 30, 1932, Serial No. 644,956.

It is evident that various changes may be resorted to in theconstruction, form and arrangement of the several, parts withoutdeparting from the spirit and scope of my invention, and

hence I do not intend to be limited to the particular embodiments hereinshown and described, but

What I claim is:

l. A hair waving device comprising a perforated tube and a tube ofabsorbent material telescoping one within the other, and an insertablecoiled sheet impregnated with an exothermic material.

2. 'A hair waving device comprising a perforated tube upon which thetress is to be wound, a tube of absorbent material insertable into theperforated tube and adapted to be moistened, and a charge of exothermicmaterial insertable into the absorbent tube, said charge being in theform of a coiled impregnated sheet.

' 3. A hair waving device comprising a tube of absorbent materialadapted to be moistened, and a charge of exothermic material locatedinside of said absorbent tube, said charge being in the form of a coiledimpregnated sheet.

4. A hair waving device comprising a tube of absorbent material adaptedto be moistened, a perforated tube telescoping within the absorbenttube, and a charge of exothermic material, located inside 01- saidperforated and absorbent tubes, said charge being in the form of acoiled impregnated sheet.

5: A hair waving device including a charge of exothermic material in theform of a coiled sheet impregnated with the exothermic material.
